GENERAL DESCRIPTION
Four
air
conditioning systems
are
covered
in
this
section. They are:
1.
The
Four-Season System (Chevrolet, Chevelle,
Camaro and Corvette).
2.
The Comfortron System (Chevrolet).
3.
The All Weather System (Chevy n).
4.
The Universal System (Chevrolet, Chevelle, Chevy
n,
Camaro)
Underhood components (that
is, the
compressor,
con-
denser
and
receiver-dehydrator)
are
much
the
same
in
type,
location
and
method
of
attachment
on all of
the
above systems. The six-cylinder reciprocating compres-
sor
is
bracket-mounted
to the
engine
and
belt driven
from
the
crankshaft pulley.
The
condenser
is
mounted
ahead
of the
engine cooling radiator
and the
receiver-
dehydrator
is
mounted
in
the refrigerant line downstream
of
the
condenser.
All
cooling system components
are
connected by means
of
flexible refrigerant lines.
Evaporator size
and
location differ from system
to
system
as do
methods
of
temperature control
and air
supply
and
distribution.
FOUR-SEASON SYSTEM
The Four-Season system used
in the
Chevrolet,
Chevelle, Camaro,
and
Corvette vehicles
may be
iden-
tified
by the
fact that
it
uses
an
evaporator pressure
control known
as the POA
(Pressure Operated Absolute)
suction throttling valve.
Both
the
heating
and
cooling functions
are
performed
by this system.
Air
entering
the
vehicle must pass
through
the
cooling unit (evaporator)
and
through
(or
around)
the
heating unit,
in
that order, and the system
is
thus referred to
as a
''reheat" system.
The evaporator provides maximum cooling
of the air
passing through
the
core when
the air
conditioning sys-
tem
is
calling
for
cooling.
The
control valve acts in the
system only
to
control
the
evaporator pressure
so
that
minimum possible temperature
is
achieved without core
freeze-up.
The
valve
is
preset,
has no
manual con-
trol,
is
automatically altitude compensated,
and non-
repairable.
The heater core will be hot
at
all times since no water
valve
is
present
in
the system.
System operation
is as
follows (See Figure 24 and 25):
Air, either outside
air or
recirculated
air
enters
the
system
and is
forced through
the
system by the blower.
As
the air
passes through
the
evaporator core,
it
receives maximum cooling
if
the
air
conditioning controls
are calling
for
cooling. After leaving
the
evaporator,
the
air
enters
the
Heater
and Air
Conditioner Selector
Duct Assembly where,
by
means
of
manually operated
diverter doors,
it is
caused
to
pass through
or to
bypass
the heater core
in the
proportions necessary
to
provide
the desired outlet temperature. Conditioned airflow then
enters
the
vehicle through either
the
floor distributor
duct
or the
dash outlets. Remember that the heater core

PRECAUTIONS IN HANDLING REFRIGERANT LINES
• All metal tubing lines should be free of kinks, be-
cause of the restriction that kinks will offer to the
flow of refrigerant. The refrigeration capacity of the
entire system can be greatly reduced by a single
kink.
• The flexible hose lines should never be bent to a
radius of less than 10 times the diameter of the hose.
• The flexible hose lines should never be allowed to
come within a distance of 2-1/2" of the exhaust
manifold.
• Flexible hose lines should be inspected at least once
a year for leaks or brittleness. If found brittle or
leaking they should be replaced with new lines.
• Use only sealed lines from parts stock.
• When disconnecting any fitting in the refrigeration
system, the system must first be discharged of all
refrigerant. However, proceed very cautiously re-
gardless of gauge readings. Open very slowly, keep-
ing face and hands away so that no injury can occur
if there happens to be liquid refrigerant in the line.
If pressure is noticed when fitting is loosened, allow
it to bleed off very slowly.
CAUTION: Always wear safety goggles when
opening refrigerant lines.
• In the event any line is opened to atmosphere, it
should be immediately capped to prevent entrance
of moisture and dirt.
• The use of the proper wrenches when making con-
nections on "O" ring fittings is important. The use
of improper wrenches may damage the connection.
The opposing fitting should always be backed up with
a wrench to prevent distortion of connecting lines or
components. When connecting the flexible hose con-
nections it is important that the swagged fitting and
the flare nut, as well as the coupling to which it is
attached, be held at the same time using three dif-
ferent wrenches to prevent turning the fitting and
damaging the ground seat.
• "O" rings and seats must be in perfect condition.
The slightest burr or piece of dirt may cause a leak.
• Sealing beads on hose clamp connections must be
free of nicks and scratches to assure a perfect seal.
MAINTAINING CHEMICAL STABILITY IN THE
REFRIGERATION SYSTEM
The metal internal parts of the Chevrolet refrigeration
system and the refrigerant and oil contained in the sys-
tem are designed to remain in a state of chemical
stability as long as pure R-12 and uncontaminated re-
frigeration oil is used in the system.
However, when abnormal amounts of foreign materials,
such as dirt, air or moisture are allowed to enter the
system, the chemical stability may be upset. When ac-
celerated by heat, these contaminates may form acids
Fig.
40-^-System Contaminants
and sludge and eventually cause the breakdown of com-
ponents within, the system. In addition, contaminates may
affect the temperature-pressure relationship of R-12,
resulting in improper operating temperature and pres-
sures and decreased efficiency of the system.
The following general practices should be observed to
insure chemical stability in the system.
• Whenever it becomes necessary to disconnect a
refrigerant or gauge line, it should be immediately
capped. Capping the tubing will also prevent dirt and
foreign matter from entering.
• Tools should be kept clean and dry. This also in-
cludes the gauge set and replacement parts.
• When adding oil, the container should be exception-
ally clean and dry due to the fact that the refrigera-
tion oil in the container is as moisture-free as it is
possible to make it. Therefore, it will quickly absorb
any moisture with which it comes in contact. For
. this same reason the oil container should not be
opened until ready for use and then it should be
capped immediately after use.
• When it is necessary to open a system, have every-
thing you will need ready and handy so that as little

The only check for proper POA valve operation is to
check the suction pressure at the valve as during a
performance test. The POA valve is an absolute valve
and will provide different gauge readings based on the
altitude where the readings are being taken. Correct
gauge reading at sea level is 29.5 psig. Gauge readings
will be one-half psi higher for each additional 1000 feet
of elevation. The following table lists gauge readings at
different altitudes. If a valve gives improper gauge
readings, it must be replaced since it is not repairable
or adjustable.

THERMOSTATIC SWITCH
(Universal and Chevy II All-Weather System)
Thermostatic switches used in Universal and All-
Weather systems differ only in the capillary tube sensing
unit.
The Chevy n All-Weather System thermostatic switch
has an air sensing capillary which is coiled and attached
to the front of the evaporator core with plastic plugs.
This type of unit is controlled by the temperature of the
air leaving the evaporator.
Universal systems make use of a thermostatic switch
with a fin sensing capillary or a self-supporting air sens-
ing capillary. This capillary controls the switch by
sensing the temperature of the metal fins or the air
leaving the fins.
Checking for Proper Operation
1.
Install the gauge set and set up the vehicle as
described under Performance Test.
2.
Movement of the temperature control knob should
result in a definite change in suction pressure and
cycling of the compressor clutch.
• If compressor continues to operate regardless of
the knob adjustment, it indicates that the points

GENERAL DESCRIPTION
The 1967 Chevrolet, Chevelle, Camaro, Chevy n and
Corvette front suspension systems are basically similar,
being of the
S.L.A.
(short-long arm) type with independent
coil springs. In the Chevrolet, Chevelle, Camaro and
Corvette the springs ride on the lower control arms; in
the Chevy II the springs ride on the upper control arms.
Spherical joints connect the upper and lower arms to the
steering knuckle. Tapered roller wheel bearings are
used.

FRONT END ALIGNMENT
Front end alignment, that is alignment of the inter-
related steering components of the front suspension sys-
tem, must be correctly maintained to assure ease and
stability of steering and satisfactory tire life.
Alignment Preliminary Steps
Several different types of machines are available for
checking all the factors of front end alignment. The in-
structions furnished with each particular machine should
be followed. In all cases, however, checks should be
made with the vehicle level and at curb weight.
Since steering complaints are not always the result of
improper alignment a check should be made to see if any
of the following conditions exist. Any such conditions
should be corrected before proceeding further.
1.
Steering gear loose or improperly adjusted.
2.
Steering gear housing loose at frame.
3.
Excessive wear or play in spherical joints or steer-
ing shaft coupling.
4.
Tie rod or steering connections loose.
5.
Improper front spring heights.
6. Unbalanced or underinflated tires.
7.
Improperly adjusted wheel bearings.
8. Shock absorbers not operating properly.
Wheel alignment should always be made with the vehi-
cle rolled forward taking out any slack in the same man-
ner as when the vehicle is traveling forward.
Caster and Camber Adjustment
NOTE: Before adjusting caster and camber
angles, the front bumper should be raised and
quickly released to allow car to return to its
normal height.
Chevelle, Camaro and Corvette
Caster and camber adjustments are made by means of
shims inserted between the upper control arm inner sup-
port shaft and the support bracket attached to the frame
(fig. 6). Shims may be added, subtracted or transferred
to change the readings as follows:
Fig.
6 - Caster and Camber Adjustment - Chevelle
Typical of Corvette and Camaro
Caster - change shims at either the front or rear of
the shaft.
The addition of shims at the front bolt or removal
of shims at the rear bolt will decrease positive
caster. One shim (1/3 2") will change caster (ap-
prox.) 1/4°.
Camber - change shims at both the front and rear of
the shaft.
Adding an equal number of shims at both front and
rear of the support shaft will decrease positive cam-
ber. One shim (1/32") at each location will move
camber (approx.) 1/5° (Chevelle and Camaro); 1/6°
(Corvette).
